By default, Chrome history that's saved to your Google Account is also added to Web & App Activity. Your activity may be used to personalize your experience on other Google products, like Search or ads. For example, you may see a news story recommended in your feed based on your Chrome history.

If you don't want to personalize your Google products, you can still use Google's cloud to store and sync your Chrome data without letting Google read any of your data. Learn more about keeping your info private.

Keep your info private

With a passphrase, you can use Google's cloud to store and sync your Chrome data without letting Google read it. Your payment methods and addresses from Google Pay aren't encrypted by a passphrase.

Passphrases are optional. Your synced data is always protected by encryption when it's in transit.

If you’re having trouble syncing with your passphrase, you may have to update Google Chrome to the latest version.

When you change your sync passphrase, all your data is deleted from Google’s servers and all your synced computers and devices are signed out. This doesn't include payment methods and addresses from Google Pay.

Your bookmarks, history, passwords, and other settings aren't deleted from Chrome on your device. When you turn sync on again, your info will save across all your devices.
